摘　　要：本文通过对国内外相应标准的分析、研究和对比，提出了用于城市轨道交通（直流供电接触网系统）中的1500V隔离开关柜的绝缘参数参考值，其原则是既要保证非常可靠而又节约成本。该文给出了主回路带电体间以及对地的净空气距离、爬电距离、工频耐受电压和雷电冲击耐受电压等多项数据。The article puts forward the reference values of insulation parameters of the 1500VDC disconnector used for the DC supply contact net system of urban railway transportation through the analysis, research and comparison of relevant standards at home and abroad under the principle of ensuring high reliability and saving cost. The paper gives the multi-term data, such as clearance air distance between electrified bodies of main circuit and the clearance distance between main circuit and ground, creep distance, power frequency withstand voltage and lightning impulse withstand voltage, and so on.

关 键 词：绝缘参数 对地净空气距离 爬电距离 工频耐受电压 雷电冲击耐受电压
